22\page migration Migration from the 0.x Series
24This guide gives an in depth description on what has changed compared
25to the 0.x release series.
27Many of these changes adjusted automatically by the
28<tt>script/</tt> tool. Those requiring manual
29update are typeset <b>boldface</b>.
31\section migration-graph Graph Related Name Changes
33- \ref concepts::Digraph "Directed graphs" are called \c Digraph and
34  they have <tt>Arc</tt>s (instead of <tt>Edge</tt>s), while
35  \ref concepts::Graph "undirected graphs" are called \c Graph
36  (instead of \c UGraph) and they have <tt>Edge</tt>s (instead of
37  <tt>UEdge</tt>s). These changes reflected thoroughly everywhere in
38  the library. Namely,
39  - \c Graph -> \c Digraph
40    - \c %ListGraph -> \c ListDigraph, \c %SmartGraph -> \c SmartDigraph etc.
41  - \c UGraph -> \c Graph
42    - \c ListUGraph -> \c ListGraph, \c SmartUGraph -> \c SmartGraph etc.
43  - \c Edge -> \c Arc, \c UEdge -> \c Edge
44  - \c EdgeMap -> \c ArcMap, \c UEdgeMap -> \c EdgeMap
45  - \c EdgeIt -> \c ArcIt, \c UEdgeIt -> \c EdgeIt
46  - Class names and function names containing the words \c graph,
47    \c ugraph, \e edge or \e arc should also be updated.
48- <b>The two endpoints of an (\e undirected) \c Edge can be obtained by the
49  <tt>u()</tt> and <tt>v()</tt> member function of the graph
50  (instead of <tt>source()</tt> and <tt>target()</tt>). This change
51  must be done by hand.</b>
52  \n Of course, you can still use <tt>source()</tt> and <tt>target()</tt>
53  for <tt>Arc</tt>s (directed edges).
56<b>The <tt>script/</tt> tool replaces all instances of
57the words \c graph, \c digraph, \c edge and \c arc, so it replaces them
58in strings, comments etc. as well as in all identifiers.</b>
60\section migration-lgf LGF tools
62\section migration-search BFS, DFS and Dijkstra
63- <b>Using the function interface of BFS, DFS and %Dijkstra both source and
64  target nodes can be given as parameters of the <tt>run()</tt> function
65  (instead of \c bfs(), \c dfs() or \c dijkstra() itself).</b>
66- \ref named-templ-param "Named class template parameters" of \c Bfs,
67  \c Dfs, \c Dijkstra, \c BfsVisit, \c DfsVisit are renamed to start
68  with "Set" instead of "Def". Namely,
69  - \c DefPredMap -> \c SetPredMap
70  - \c DefDistMap -> \c SetDistMap
71  - \c DefReachedMap -> \c SetReachedMap
72  - \c DefProcessedMap -> \c SetProcessedMap
73  - \c DefHeap -> \c SetHeap
74  - \c DefStandardHeap -> \c SetStandardHeap
75  - \c DefOperationTraits -> \c SetOperationTraits
76  - \c DefProcessedMapToBeDefaultMap -> \c SetStandardProcessedMap
78\section migration-error Exceptions and Debug tools
80<b>The class hierarchy of exceptions has largely been simplified. Now,
81only the i/o related tools may throw exceptions. All other exceptions
82have been replaced with either the \c LEMON_ASSERT or the \c LEMON_DEBUG
85<b>On the other hand, the parameter order of constructors of the
86exceptions has been changed. See \ref IoError and \ref FormatError for
87more details.</b>
89\section migration-other Others
90- <b>The contents of <tt>graph_utils.h</tt> are moved to <tt>core.h</tt>
91  and <tt>maps.h</tt>. <tt>core.h</tt> is included by all graph types,
92  therefore it usually do not have to be included directly.</b>
93- <b><tt>path_utils.h</tt> is merged to \c path.h.</b>
94- <b>The semantic of the assignment operations and copy constructors of maps
95  are still under discussion. So, you must copy them by hand (i.e. copy
96  each entry one-by-one)</b>
97- <b>The parameters of the graph copying tools (i.e. \c GraphCopy,
98  \c DigraphCopy) have to be given in the from-to order.</b>
99- \c copyDigraph() and \c copyGraph() are renamed to \c digraphCopy()
100  and \c graphCopy(), respectively.
101- <b>The interface of \ref DynArcLookUp has changed. It is now the same as
102  of \ref ArcLookUp and \ref AllArcLookUp</b>
103- Some map types should also been renamed. Namely,
104  - \c IntegerMap -> \c RangeMap
105  - \c StdMap -> \c SparseMap
106  - \c FunctorMap -> \c FunctorToMap
107  - \c MapFunctor -> \c MapToFunctor
108  - \c ForkWriteMap -> \c ForkMap
109  - \c StoreBoolMap -> \c LoggerBoolMap
110- \c dim2::BoundingBox -> \c dim2::Box
